Why these are different
Most free audio checkers upload your file to a server. These don't — every measurement runs locally in your browser with the Web Audio API, using the same analysis engine as TrackGleam's mastering app, so what a tool reports is exactly what you get when you master. No signup, no watermark, no upload.
Found a problem? Every tool links straight into TrackGleam, where you can master your track free and download a streaming-ready WAV — with an optional AI-tuned master for $1.99.
